METAL DOOR.

Application filed February 24 To all whom it may concern:

Be it known that I, OLOF H. JAooBsoN, a citizen of Sweden, residing at Garfield, State of Kansas, have invented certain new and useful Improvements in Metal Doors, of which the following is a specification.

My invention relates to improvements in metal doors having, preferably, both metal and glass panels, and the invention relates more particularly to means whereby a broken glass panel can be readily removed and replaced by a new one without taking the door apar.

In the accompanying drawing, which illustrates the invention: Figure l is a vertical section of a metallic door embodying my invention. Fig. 2 is a detail perspective of a clamping-member constituting an important feature of the invention. Fig. 3 is a detailperspective of a locking-member employed in carrying out the invention.

In the present instance, the frame of the metal door is-of usual construction, it consisting 'of rails and stiles 1 and 2, removable top and bottom plates 3 and 4, and moldings 5 and 6, respectively. The plates 3 and 1 are securcdby the means shown in Fig. 1 which engage the flanges of the plates '3 and 1.

7 designates the lower panel of the door, consisting of the customary sheet metal plates spaced apart to receive the usual asbestos or other fireproof filling 8. Panel 7 is reliably held in place by two lockingmembers 9, each consisting of a channeled central portion 10, arms 11, bent at right angles to said channeled portion, and marginal flanges 12 bent inward toward the channeled portion 10. The lower moldings 5 have their adjacent ends 18 bent parallel to each other to bear against the sides of the panel 7, and are then folded to constitute locking-strips 14, which interlock with the marginal flanges 12 and thus firmly hold the two locking-members 9 in place.

15 designates a glass upper panel supported upon a locking member 9, which enthe lower ends of Specifieationof Letters Patent.

the moldings 6, said lower ends being bent in the same manner as the ends of the moldings 5. The upper moldings 6 are bent inward and upward to bear against the upper portion of the panel 15, and their margins 17 are bent outward and downward to be gripped by the inverted U-shaped clampingmember 18, having brackets 19, the ends of which bear against the top plate 3 and against the holding means of plate 3 thus reliably holding the clamping-member 18 in position against said margins 17 of the moldings 6. Should the panel 15 become cracked or broken it can be readily removed and another substituted therefor by removing the top plate 3 of the door and then taking off the clamping member 18. When a door without an intermediate rail and but one large glass panel is desired, only the bottommost member 9 is=retained to support said panel, and the U-shapcd clamping-member 18 is slipped over the inner ends 17 of moldings 6, to secure the upper end of the panel in place.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

In a metal door, a frame having a molding'the sides of which at the molding top are extended inwardly, and upwardly to form a pair of panel gripping parts, an inverted U-shaped' clamping member engaged with said gripping parts, a top plate on the frame above the molding, means on the frame to removably hold the top plate, and a series of U-shaped brackets having their connecting or base portions secured to the member and having the free ends of their legs freely movable and engaged with the top plate and having the sides of their legs engaged with said holding means for the top plate.

In testimony whereof I atlix my signature. in the presence of two witnesses.
